Hey Russ!!!
The 2 weeks strength/2weeks endurance is right form Pavelís recommendations form the DD site, RKC book and elsewhere. Charles Poliquin recommends similar segmented cycles. One looses strength characteristics relatively slowly, especially when endurance work is power/strength-endurance oriented.

When you mention cycles, how long are these?
Good to see you Amigo!
